Best resistors for use in phono stage?

Vishay Z foils aka Texas Components TX2575 highest resolving, transparent I've used, I don't really hear a specific sound quality from these, consider them neutral. Takman carbon film when I'm looking for a bit of warmth. I'd like to try some of the AN in my next project.

Vishays can be stacked if more wattage needed, gets pretty pricey here.

Wattage. What's the importance of this?

For your purpose—cartridge loading, the lowest wattage resistor will be WAY more than you need because very little power is passing through it.  You can use the lowest rated resistor you can find.

Larryi is right.

All components have sonic signatures. Whether a particular part is suited to a system can only be evaluated in situ.

Beware of FanBoy recommendations.
